Configure the Serial Ports for Modbus Master

When you use a serial port on the AADvance controller for Modbus master (Modbus

RTU), you have to configure the serial port. In particular, you have to set the port

type to suit the arrangement of the physical connection. To configure the serial port,

do the following:

1) Select 9110 Processor on the Project Tree View to open the 9110 Module

Editor.

2) Select the Serial Ports tab.

 The Serial Ports editor dialog box opens.

3) Locate the chosen serial port (S1-1 for example)in the editor and set the Type

parameter:

 If the physical connection is a full duplex (4-wire) point-to-point connection to

a single slave, choose RS485fd.

 If the physical connection is a full duplex (4-wire) connection to multiple slaves

(tri-state outputs on the slave transmitters), choose RS485fdmux.

 If the physical connection is half duplex (2-wire), choose RS485hdmux.

4) Set the remaining communication parameters from the drop down lists, to match

those used by the slave devices; click Apply.

5) To restore the default values, click Default then Apply.
